Abstract: 235U decays by alpha particle emission to 23I Th. The decay scheme of this nuclide is very complex, with more than 20 alpha branches. Recommended values for Palpha of this nuclide are based on measurements carried out in 1975. This work presents the results of new measurements made with SI detectors and sources of enriched uranium in the frame of the EUROMET 591 cooperation project. The use of improved measurement techniques and numerical analysis of spectra allowed a new set of P alpha values for 13 lines with improved uncertainties to be obtained.
